[pfSense] Gateway Group / Failover WAN setup question

2014-03-11 Thread Justin Edmands
pfSense List,
We currently run a gateway with a single WAN connection. We are adding
another WAN connection in the near future. The WAN will be for Failover and
not Loadbalancing.

After reading the pfsense docs and watching a few youtube videos; I'll add
a gateway group and create the proper Tiers to assign the Failover1 and
Failover2 groups. I'll create external DNS entries and have each WAN aware
of that respective DNS in the General Setup.

The main questions:
The current rules all read * for the Gateway. Do all of my current LAN,
OpenVPN, and IPSec rules need to be altered to include the Gateway as the
new Failover1 rule?

Do I need to clone each and every rule to have:
rule 1 of 2 say WAN_FailoverGroup1
 -and-
rule 2 of 2 say WAN_FailoverGroup2

?

Those that rely on the WANs, yes. Rules to allow traffic to pass between 
your VPNs and LANs do not need the gateway to be changed. It's worth 
noting that incoming rules (i.e. WAN rules) should not have their 
gateway changed either.

No - you don't want two copies of each rule. Assuming you've two 
connections: WAN1 and WAN2, you'd define a single gateway group - let's 
call it 'Failover1to2' for example. WAN1 would be Tier 1 and WAN2 would 
be Tier 2. You would then modify each outbound traffic rule to use 
'Failover1to2' as the gateway.


If both connections are similar speed/performance, you might want to do 
a little policy-based routing. You could define a second gateway group 
'Failover2to1' which reverses the tiers. This might be useful for 
traffic you want to keep off your 'main' WAN connection (I use this to 
send SIP and SSH traffic over the second WAN here, so that performance 
doesn't suffer when the primary connection is heavily loaded).


Kind regards,

Chris
